TO ALL WHOM IT MAY CONCERN: p

Be it known that I, CHARLES T.LIERNUB., oi Frankfort-on-'the-Main, Germany, `have invented a new and useful Improvement in vPneumatic Sewerage; and I do hereby'd'eclare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing, forming a part ot' this specification, Vin whichligure 1 represents a longitudinal vertical section of this invention.

Figure 2 is s. plan'or top view of the same.

Similar letters of reference indicate like parts.

The object '21 this inventionis to empty privies and their pipes at any moment by connecting them with an air-tight reservoir sunk in the street, by means ofl pipes which vare provided with. stop-cocks, in such a manner that when all the stop-cocks are closed the air can be exhausted from said reservoir, and by opening one of the stop-cocks after the other the contents of the several privies are sucked into said reservoir without the least inconvenience from the emission of a bad odor. i

A represents a reservoir which is made air-tight, oi' boiler` iron or any other suitable material. From this reservoir extend pipes, B, to lthe privics orsinks in the surrounding buildings, and said pipes are provided with stop-cocks, a, so that the sameIcan vbe opened and closed at any moment. The reservoir A is provided witha pipe, J1, by means of which it can be connected with an air-pump, so that the air can be exhausted from said reservoir, provided thestopcocks in the connecting pipes Bv are closed. If a privy or sink is to be lemptied the stop-cock in the pipe connecting the same with the reservoir is opened, and the pressure of the atmosphere forces the contents ot-said sink or privy into the reservoir. By this operation all emission of a bad odor is avoided, and atI the same time a current Yotfresb air is made to pass through said sink or privy, rendering the same clear and free from all bad odor.- I f the 'reservoir is full, or whenever it is desired to empty the same, a

:ir inodorous process is employed, by connecting the pipe c with a pneumatic wagon. The pipe c passes down near lto the bottom of thereservoir, and the pneumatic wagon is a well-known device, consisting' of al strong tank which is carried through the streets ou suitable Wheels, and from which the air is exhausted either in a particular yard or by an air-pump attached to the tank and pperated by the motion of-'the wheel or wheels which support said tank. By this arrangement the operation of cleaning privies or sinks and their pipes is rendered comparatively simple and easy. It can beeifected without producing the least inconvenience to persons in the neighborhood, and after the first cost of erecting the requisiteapparatusvery little ex'pense is created by the operation; l

I claimv :is new, and desire to secure by Letters Patent- The method herein described of cleaning privies, sinks, &'c., consisting of an air-tight reservoir, A, sunk in the street and connectingwitb several privies and sinks by pipes, B, provided with stop-cocked, substantially and for the purpose set forth. i
